My invention relates to door frames and particularly to an improved buckhaving numerous advantages hereinafter described.

An object of the invention here described is to providea metal buckadapted to receive nailing blocks for supporting a j amb, the

construction being such that added strengthand stabilityaresecured.These advantages are present by' reason of peculiarities in design; forexample, the depth of the channel-y shaped buck is reduced, therebyreducingthe distance between the jamb and the edge of the masonry wall.This lessens the extent of overhand and shortens the leverage tending toseparate the buck from the wall unde laterally exerted blows. Y

The rigidity of the structure is increased also by providing a doublethickness of metal at the sides of the channel. The strength of thechannel is also increased by eliminating cutout portions ordinarilyprovided in the web of the channel, the lateral positioning of thechannel being secured by means of continuous strips.

By reducing the depth of the channel, the size of the wood blocks iscorrespondingly reduced with a savin of material.

Additional strengt against lateral blows is provided byv utilizingcontinuous strips from top to bottom of the channel vinstead of theusual ears arranged in spaced relation.

Inasmuch as the projecting or exposed portions of the buck should bepainted and as paint will not adhere to black or blue iron sheets, it isessential that these portions be galvanized or similarly coated. Byreason of the construction shown the channel member i stood byvreference to the accompanying drawings, in which Fig. 1 is aperspective sectional view of a frame arranged in accordance with my in-W vention; i

through; and, f

Y lF ig. 2is a transverse sectional view there- 'g. 3 is-a .fra mentarysectional view of a modification of the construction. d

Inv the drawings, themasonry `wall is indicated at 10, the jamb at 11and the wood nailing blocks at 12.7. rIhe buck is of channel formcomprisinga ,web '.613 and flanges 14. The margins 15 of the Aflangesproject `at right nangles'and constitute plaster terminals. The .channelportion maybe formed of gal-l vafizedmaterial `toadapt the exposedportionsl .to receive paint;` l

- placedasshown and welded tothe -flanges of '55 Chnnelf I -pNlails 17project through the two thicknesses of metal .and hold the wood blocks.Other nails 18 are used for securing the-jamb tothe nailing blocks. i

The strips attheir'rearward edge project asubsta-ntial,distance beyondVthe limits of thewchanneland'closely lit the masonry wall. As a nieanslfor anchoring the plaster to the strips, I strikeout loops19,ithese being ar ranged in suitablefclosely spaced relation toaccomplish the desired result. Wall anchors i 20 having hooked ends thatengageinthe apertures V`formed by striking ,out the loops, serve to holdthe structure in place.

Inthe modification shown in Fig. 3 the so buck comprises a web 21 andflanges 23 which may be formed of black iron, the strip 23 has themargins 24 forming a plaster terminal and may be of galvanized metal.Otherwise the construction is the same and the function is the same asthat already described.

Obviously the construction is capable of some modication and I do notwish to be limited except as indicated in the appended claims.

I claim:

1. In frame construction, the combination .of a channel shaped buck, anda continuous strip welded to a` iiange of the channel and extendingreadwardly a substantial distance L beyond the limits of the channel inline with the flange, and plaster anchors formed in said strip. y

2. In door frame construction, the combination of a buck of relativelyshallow chanlo nel construction, adapted to he mounted with the flangesprojecting into the door opening, a wood member in the channel adaptedto receive a jamb, and a flat, longitudinally continuous strippermanently secured to the outer face of a channel flange with the inneredge of the strip projecting a substantial distance beyond the limits ofthe channel and adapted to lie alongside of a wall.

3. In a door frame, the combination of a relatively shallow channel withthe margins of the flanges bent to provide plaster terminals, andlongitudinally continuous flat strips welded to the outside iac'e's ofthe flanges of the channel and projecting rearwardly from the limits ofthel channel.

4. In a door frame, the combination of a relatively shallow channel withthe margins of the flanges bent to provide plaster terminals, andlongitudinally continuous flat strips welded to the outside faces of theflanges of the channel and projecting rearwardly from the limits of thechannel, and plaster anchors formed in said strips;

5. In a door frame, the combination of a relatively shallow channel withthe margins of the ia'nges bent to provide plaster terminals, andlongitudinally continuous flat strips welded to the outside faces of theflanges of the channel and projecting rearwardly from the limits of thechannel,` and loops struck out from said strips to serve as plasteranchors.

6. In a door frame,V the combination of a relatively shallow channelwith the margins of the ilanges bent to provide plaster terminals, andlongitudinally'continuous flat strips welded to the outside faces of theflanges of the channel and projecting rearwardly from the limits of thechannel, Vwoodumembers in said channel and a j amb secured to the woodmembers.

In testimony whereof I have aiXed my signature.
